Details about seismic design of retaining wall
This construction video tutorial provides brief discussion on the seismic analysis and design of retaining wall. The discussion is made for the following purposes :-
Highlights the restraints related to existing process that is applied to calculate seismic earth pressures on retaining walls. These restraints comprise of troubles associated with utilizing the M-O equations for specific combination of seismic coefficient and backslope over the retaining structure or toward backfill conditions where the soils are not cohesionless or consistent.
Formulate guidance on determination of the seismic coefficient that is utilized to carry out either a force based or displacement based assessment of the seismic performance of retaining walls. There is great perplexity in current practice on determination of the seismic coefficient, specifically for diverse wall types.
Offer suggestions on approaches which should have been utilized for the seismic analysis and design of alternate wall types that is applicable to create LRFD specifications.
For more details, watch the following exclusive video tutorial presented by Professor Kousik Deb, department of Civil Engineering, IIT Kharagpur.
